To all whom it may concern;

Be it known that 1, CARL J. LANDIN, a'

of Boston, the county of Suffolk and State of lr'iassachusetts, have invented an improve ment in Machines for Feeding Fabrics and the like, of which the following description, in connection with. the accompanying drawings, is a specification, like letters on the drawings representing like parts.

1 This invention relates to the feeding of fabrics or other materials in coating or other machines.

The character of the invention. may be best understood by reference to the following description of an illustrative embodiment thereof shown in the accompanying dra wings, wherein:

Figure 1 an interrupted, vertical, longitudinal section through a coating machine illustrated herein as embodying my invention; Fig. 2 on an enlarged scale illustrates a r ll shownin Fig. 1 and connections for starting the fabric into the machine; Fig. i on an enlarged scale illustrates a take-up roll shown in Fig. 1; Fig. 4 is plan of Fig. 3; Fig. "5 on an enlarged scale illustrates the construction of an end of an apron used in the machine; Fig. 6 is a side eleva tion of Fig. 5; Fig. 7 on an enlarged scale illustrates a hook plate shown in Fig. 2 forv detachably connecting the fabric to the apron; Fig. 8 is a side elevation of Fig. 7 Fig. 9 is a view similar to Fig. 7 showing the fabric connected to the hook; side elevation of Fig. 9; Figs. 11 to 16 are diagrammatic views illustrating steps in theprocess of introducing the fab ric to the machine; and Figs. 17 and 18 are details to be referred to.

Referring to the drawings, the illustrative a}')paratus shown herein as embodying my invention comprises a let-off roll 11 (Fig. 1) on which the fabric to be treated may be previously wound. Tointroduce this roll into the machine it may he slipped on to a rectangular shaft 13 having rounded ends for insertion in open bearings on brackets 17 projecting laterally from the feeding-in end of the machine frame 19. The fabric or material on the let-0E roll may be led diagonally upward to and over a rubber coated or equivalent roll 21 journaled in bearingsin the machine frame and driven desired.

by any suitable mechanism, not shown.

Said fabric passes beneath a scraper coating knife located above said roll and having trunnions 25 j ournaled in boxes 27 adapted to be vertically adjusted in guides 29 by screws 31 and hand wheels 33.

The fabric led between the roll 21 and knife 23 may receive a coating of rubber a portion of the fabric on the roll 21 back of the knife 23. As the fabric is fed between said knife and roll the rubber comspread or distributed thereby in the form of a thin coating on the fabric.

In order to dry the fabric thus coated the fabric is led a considerable distance from the coating roller 21 to and over a guide roller Fig. 1) preferably larger in diameter than the roller 21 and mounted on a shaft 37 journaled in suitable bearings on themachine frame. The guide roller may be composition or other material. This materm]. is usually viscous and may be laid on position will crowd against the knife and be 7 driven from the shaft of the coating roll 7 by any suitable gear connections (not shown) including a suitable clutch for controlling the starting and stopping of the guide roller. The drying of the coating may be assisted by heat The fabric is led from the guide roller 35 downwardly and thence diagonally forwardly toward the feeding-in end of the machine to a take-up roll 39. To permit this roller to be readily introduced into or taken from the machme for purposes hereinafter described said roller may be slid on a square shaft 41 having rounded ends for insertion in open bearings T3 in brackets 45 pro ectlng laterally from the machine frame.

This take-up roll may be driven in any radiators, not shown, if

suitable manner by means not shown herein.

Heretofore, so far as I am aware, the introduction of the fabric into the machine has been by a slow and crude process. This hasbeen effected by sewing a long, introductory strip of cheap material to the end of the fabric. The end of said strip is then led manually upwardly over the rubber.

coated roll 21., beneath the coating knife 23 thence rearwardly to and over the guide roller 35 at the remote end of the machine; then under said roller back toward the feeding in end ofthermachinewhere it is secured to the take-up roll 39. Not only does the leading in of the fabric in this manner require a great deal of time, but also it is 'A similar strip, also, must be sewed at the impossible to sew the leading strip tothe fabric to be treated without causing a series of wrinkles in the fabric adjacent the seam forming the juncture thereof with said strip when said strip is tensioned as in feed.-

ing. In order that the thin coating may be properly applied it is necessary that the fabric should be absolutely smooth. This w'vrinkling prevents aproper application of the coating material for several feet ZLCl]&-'

cent the seam and as aresult this portion of the fabricis Wasted. Furthermore, it is nee essary to watch th'eleading in strip at the guide roller and manually smooth out the wrinkles which are bound to occur at this point in order that the followingfabric may be smoothly guided over said roller.

trailing or last end of the fabric to pass through the machine in order that the end of the fabric may not trail loosely through the machine after leaving the roll 21.' Here again at the juncture of the trailing strip with the fabric occurs the objectionable wrinkling of V the fabric with consequent waste of a portion of the fabric at said seam due, as stated, to the inability to properly coat a wrinkled fabric.

By my invention the above and other objections to the above described crude method of feeding the fabric through the machine are overcome. By my invention it is unnecessary to sew}long. introductorv and trailing strips or aprons at the ends of the'fabric'to cur'ely retaining 5 be treated but, instead thereof, I use means whichl will now describe. As shown herein this means comprises an apron or strip 47 of canvas or other strong material of sufiicient length to extend from the coating roll 21 or feeding-in end of thev machine rearwardly to the guide roller 35 and thence Jn'aterial. The superposed parts may be then folded in plural ply form thereby sethe. tips on the ends of the apron.

To connect an end of'the apron to the take-up roll, eyes 51 (Figs. 4 and 5) may be formed in the apron adjacent the inner edges of the tip on such ends said eyes being adapted to receive screws 53 or equivalent, pro ect ons spaced on said take-up .roll at "points correspondingto the positions of the eyes 51. When the eyes are placed on said screws andth'e roll is rotated, the screws will engage'theinner edge'of the apron tip 49 and the apron will be drawn a pull evenly distributed along the tip without wrinkling.

This connection is superior to 7:

the mode of attachment hitherto .used i wherein the apron end was withoiit anyspreader tip and the connection of the apron to the roll was had merely by passing the apron endonce aroundthe roll and tucking V the same in under the standing partof the apron, thereby forming bunches and Wrinides which injured the coating on the fabri subsequently wound on the 'roll. f

While in most instances} the tip drawn canvas apron will constitute a si'ifiic ently smooth foundation cover ng for the fabrics wound on the roll, yet in some cases where very delicate fabrics are to be wounda cushion surface of greater smoothness may be hadby securing a-pad to the apron ad acent its tip. This pad may be of any suitable material conveniently formed of two' layers of canvas and an intermediate'layer of felt stitched together andlto the portion 7 of the apron beneath the same.

circumference of the roll. ;As stated, each end of the apron is provided witha spreader This pad should be of a length corresponding to thea tip as l9 and each end may also be provided with a pad. exchangeable end for end.

Having described the means for roll, I will now describe means for detach ably connecting the opposite end .of said roll 11 referred to at the feeding-in end of the machine. For this purposethere is'provided a doublehook (Figs. 2'and 7 to 10) apron with the fabric wound on the let-OE comprising a narrowzplate 57'- preferably curved to conform to the contour of the Thus. the apron is rendered r 95 detach- V ably connecting the apron with the take up take-up roll and of a length preferably some what greater than the width of the material to be fed and having its edges bent over toward one-another to formhooks57, 57

Oneof these hooks may be connected to the apron f7 and the otherinay be connected to the material to be fed. To assist in secur- '7 ing the fabric to the hook 57 there may be provided a long, narrow clamp strip 59 .of metal or'other suitable material. To facilitate its clamping operation and preventsaid P strip from being separated from said hook 57 or misplaced, said strip may be provided with fulcrum arms 61 having ends secured to the opposite ends of the strip 59. These arms project substantially perpendicularly from said strip and are adapted to parallel the ends of the hook plate 57. To permit said strip to swing about the end of the hook 57 b as more fully hereinafter described, said side arms may have flanges 63 slotted as at 65 to receive fulcrum pins 67 projecting from the opposite ends of the hooks 57 To facilitate the introduction of said pins into said slots, saidfianges may be-slitted as at position suitable construction. Before winding the fabric on this roll, first a tip 4-9, of an apron 4:7 such as described is connected to the screws 53 of an empty roll in a manner similar to that described for the take-up roll. The apron is then wound on the roll. A hook plate 57 is then connected'to the last wound end of the apron 4:7 by inserting the metal tip 19 of the latter into the hook end 57 (Fig. 11). The tip 49 is somewhat greater in width than the depth of the hook end 57* and therefore projects beyond the entrance to said hook end. As a result the apron wraps around the edge of said tip and extends along the outside of the hook endso that when pulled ittends to maintain said tip securely seated in said hook end. The hook 57 having been connected to the apron 47 as shown in Fig. 11, the hook plate 57 is then connected to an end of the'fabric to be wound on the roll. For this purpose the hook plate 57 and an end portion of the apron is folded back so that the hook is in: verted and rests on the roll as shown in Fig.

12. An end portion of the fabricis thenf laid on the hook plate and the clamping strip 59 is rocked from its full line position shown in Fig. 12 to its dotted position 1n said figure, said strip then being in a position on the fabric at the entrance to the throat of the hook 57 The clampstrip 59 is then pressed downwardly to the throat of the hook and slid on the fulcrum pins 67 into said hook, carrying with it the fabric which follows or wraps about said strip, the latter with the fabric wrapped about it being then inclosed in the hook 57 The hook plate 57 is then dropped back to its shown in Fig. 11 and the roll rotated to bring the hook plate into a position to rest on top of said roll as shown inFig. 18. The hook plate when dropped back to the position shown in Fig. 11 is again inverted and as a result the fabric will wrap about the outer edge of the clamp strip which should be of a width to project somewhat beyond the end of the hook and when pulled will tend to force or seat the strip into said hook with a force proportional to the pull on the fabric. Preferably the end of the fabric attached to the hook 57 should be of a length sufficient to wrap about the edge of said hook and lie between the standing portion of the fabric thereat and the outer face of said hook thereby adding to the security of the connection of said hook with said fabric. and the fabric to be treated is completely wound thereon. The end of the fabric last The roll is then rotated vvound is then connected to another hook platev 57 similar to the one described for connecting'the-first wound end of the fabric to the apron on the roll. For this purpose such hook plate is laid upon the roll as shown in Fig. 14:, and the last wound end of the fabric is folded back to overlie said hook plate and is connected thereto in a manner similar to that previously described. The hook is then dropped back into the position shown in Fig. 15 and'the fabric is completely wound on said roll and may be secured thereto in any suitable manner. Herein this is effected by a securing pin 70 (Fig. 17) comprisingwire legs 71 and 73 connected by a coil spring 75. The leg 73 may have an inbent prong end 7 3 In use the head 71" of the leg 71 is inserted in the hook end 57 18) and the prong leg may be pulled away from the head carrying leg and its prong inserted into the fabric on the roller. tion of said legs will tension the spring and securely hold the plate 57 to the-roll and prevent unwinding of the fabric while the roll is being carried from the winding machine to the fabric coating machine. After the roll reaches the coating machine it is placed on the arms 17 shown at the left of Fig. 1. The fabric is then in readiness to be connectedto the end of the apron already in the machine. For this purpose the hook plate is released from the roll and'led up to the end of the apron already in the machine at the coating roller and the tip of said apron is inserted in the hook end 57 of the hook plate 57, as shown in Fig. 16. The fabric is now connected to the machinein readiness to be fed therethrough. The machine is started and the coating knife and apron 17 with the fabric connected thereto is fed into the ma chine. The coating knife 23 is raised to permit the passage of the hook 57 between the latter and. the coating roll 21, whereupon the knife is lowered into engagement with the fabric and the coating substance is laid on the fabric above the roll back of the coating knife 28 as described. The machine continues to operate until the entire length of the fabric has been coated. The coating knife 23 is then raised to permit the hook The separaplate 57 connecting the trailing end of the fabric with the apron first wound on the let-ofi roll to pass beneath said knife. This apron then follows the trailing end of the fabric through the machine from the coating roll over the guide roll 35 thence to the take-up roll 89. The arrival of the end of the apron at the take-up roll marks the completion of the winding of the fabric on the latter. The end of the apronis then disconnected from the end of the fabric at the take-up roll simply by slipping the apron tip out of the hook end 57 The take-up roll is then/removed from the machine and'an "empty roll inserted in its stead the end, of the apron remaining in the machine at the take-up roll being then hooked over the.

take-up'rcll' screivs 53 as before. By this arran ement the apronfollowing the trail ing end of the fabric remains in the machine in readiness to lead in the mtroductory end 7 of the next fabric to be treated. Thus there ,is always anapron 1n the machme and it 1s merely 'necessary'to connect one end of said apron to the take-up roll and the other end to the fabric to be treated to feed the fabric through the machine. Nofurther attention on'the part of the operative is necessary until the fabric is completely Wound on the take-up roll. V

In some instances instead of always plac inga new roll of material at thejfeeding-in end of the machine, it is desirable to apply one or more additional coatings to the same fabric.

the let-ofl roll emptied by said operation and the fabric is connected to the apron 1n the machine and passed therethrough to receive another coating as before. i

It Will be apparent that by my invention the long introductory strip of material previouslysewed to'the opposite ends of the fabric to be treated is eliminated; it is not necessary that the introductory end of the} fabric to be treated, be manually led from the coating roll around the guide roll to the take-up roll as has been previously necessary, but there is always an apron .in the ,machine in. readiness to lead in the fabric;

the apron by the hook and tip connection described may be quickly and easily attached and detached from the fabric With out the time loss hitherto occasioned in seW- ing the ends of the fabric to strips; there is no wrinkling at the connection ofv the apron i with the fabric but on the'contrary, the latter is maintained smooth throughout and Withoutany loss of material such as has previously been had by old methods. It is not necessary to Wait for the trailing apron .to Wind up on the take-up roll since the apron is disconnected from the fabric on its arrival at the take-up roll. One apron suffices Where t o strips previously have been necessary, owing to the fact thatthe same apron is used for conducting the trailing end of the fabric from the co'ating'ro-ll to the take-up roll and thenfor conducting the introductory end of the next fabric to be treated. i

' While I have described my invention for f purposes of illustration asappliedto a coating machine itwill be understood that it also applies to a variety of other machines.
